vuejs2 - Vuevalidate 异步验证结果到一个循环

Question

我正在使用Vue 验证

我的 vuevlidate 中有以下内容

      validations: {
        user_form: {
            email: {required,email, isUnique(value) {
                    // standalone validator ideally should not assume a field is required
                    if (value === '') return true;
                    // simulate async call, fail for all logins with even length
                    return new Promise((resolve, reject) => {
                       this.$http.post("v1/user-management/users/email-registeredi",{email:value}).then((res)=>{
                            console.log("res is ", res);
                            resolve(true);
                        },(err)=>{
                            reject(false)
                        })
                    })
                }},
            role: {required},
            password: {required}
        }
    },

上面创建了一个无限循环的http请求，尤其是当它出现错误时

我哪里错了

你不需要使用“new Promise”，因为 vue-resource 已经这样做了。尝试这个：

validations: {
    user_form: {
        email: {required,email, isUnique(value) {
                // standalone validator ideally should not assume a field is required
                if (value === '') return true;
                // simulate async call, fail for all logins with even length

               return this.$http.post("v1/user-management/users/email-registeredi",{email:value}).then((res)=>{
                    console.log("res is ", res);
                    return true;
                },(err)=>{
                    return false;
                });
            }},
        role: {required},
        password: {required}
    }
},
